Ariana Grande's One Last Time has risen up the charts after fans kicked off a campaign to get it to the top spot.

The pop star's song, which was first released in 2014, re-entered the iTunes charts and has been steadily rising.

Fans are hoping to get the song to the number one spot to remember the victims of the Manchester terror attack, which killed 22 people and injured 119.

The track briefly reached number one before dropping back down.

Following Monday's atrocity, people started sharing clips of the pop star singing the song at the concert, with one saying it had now taken on a 'whole new meaning'.

It comes after the singer called off two London concerts and five in Europe, Arian's representatives said on Wednesday.

Monday's bombing also resulted in the cancellation of next week's London premiere of the superhero film Wonder Woman and increased security for a music festival this weekend featuring pop star Katy Perry in the northern English city of Hull.

Ariana, 23, who tweeted earlier this week that she was "broken" by the Manchester attack, had been due to perform on Thursday and Friday at London's O2 arena as part of her Dangerous Woman tour.

Both shows have been cancelled, as well as performances in Belgium, Poland, Germany and Switzerland through June 5, her record label said in a statement.

"Due to the tragic events in Manchester the Dangerous Woman tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost," the statement said.

"Our way of life has once again been threatened but we will overcome this together."

Concert promoter Live Nation said ticket holders will get refunds.

The pop singer, 23, was unharmed in the attack and was photographed arriving in Florida on Tuesday to be with family and friends.
